8a+a-3=6a-2a-3
Answer:
Step-by-step explanation:
Let the equation of the line is y = mx + c
where m = slope = 3
and c = y-intercept
Now the equation of this line will become
y = 3x + c
Since this line passes through (2, )
so = 6 + c
c = - 6
=
So the line will be y = 3x +
Answer:
d. there is a 95% probability that the true average earnings are between $3525 and $4425 for all students.
Step-by-step explanation:
95% confidence interval $3,525 < µ < $4,425 suggests that (choice d) there is a 95% probability that the true average earnings are between $3525 and $4425 for all students.
This result also suggests that (choice a) the true average summer earnings is not $4500, because our specific confidence interval does not contain the value $4500. But 95% probability is about the interval $3,525 < µ < $4,425, not the value $4500.
